Mobil 1 AF
Mobil 1 EP
Castrol Edge
Castrol EP (not sure it is ACEA A5...)
Pennzoil PP
Pennzoil Ultra Platinum (non D1G2)
Personally, I have been using PUP in my TGDI cars without issue, but as some have pointed out D1G2 has merit and I'm looking to switch my stash over to one of the oils above. When I initially started considering doing my own oil changes I used M1 EP on my car (this was 4 years ago.) Since then I had a period where I used Castrol Edge (based on a recommendation of my Grandfather who is a small engine mechanic), and more recently to PUP because from everything I read, it seemed to be "one of the best around."
Look forward to hearing what you guys have to say. I know whatever I put in my ride (even if it was Supertech Full Synthetic) will be just fine, but I also like hearing people out who have more information than I do.
You never even mentioned your OCI length. Without knowing, you may be able to save money and use a house brand.
